Firefox 5 is giving the message "This Connection is Untrusted" when attempting to go to a secure site. I'm able to get to the same site when using IE8 or Chrome.

The site doesn't send a required intermediate certificate (VeriSign Class 3 Extended Validation SSL CA)


You can copy and paste the red certificate text to a .cer file and import that file in Firefox.
